In 1842, Matteucci introduced and described the term action potential after showing that the nerve of a suitably prepared frog limb when placed over the muscle of a similarly prepared limb and stimulated could contract the muscle below it. 5. In 1868, Julius Bernstein accurately defined the concept of action potential that prevails today.
One origin for the sinus arrhythmia may be the vagus nerve which mediates respiration as well as heart rhythm. The nerve is active during respiration and, through its effect on the sinus node, causes an increase in heart rate during inspiration and a decrease during expiration. The effect is particularly pronounced in children.

Walter Gaskell's demonstration in 1882 that it was possible to block the passage of contraction from auricle to ventricle in the frog heart by means of a clamp spurred Joseph Erlanger (1906) to prevent, by similar means, impulse conduction through the bundle of (Wilhelm) His jun. (1893) in the mammalian heart.
